68add5f364 ath79: mikrotik: use OpenWrt loader for initram image
Return to using the OpenWrt kernel loader to decompress and load kernel
initram image.

Continue to use the vmlinuz kernel for squashfs.

Mikrotik's bootloader RouterBOOT on some ath79 devices is
failing to boot the current initram, due to the size of the initram image.

On the ath79 wAP-ac:
a 5.7MiB initram image would fail to boot
After this change:
a 6.6MiB initram image successfully loads

This partially reverts commit e91344776b.

An alternative of using RouterBOOT's capability of loading an initrd ELF
section was investigated, but the OpenWrt kernel loader allows larger image.

 WiFi4_5G   94:10:3e:xx:xx:71   caldata@cal_ath9k_pci

Installation from Serial Console
------------

1. Connect to the serial console. Power up the device and interrupt
   autoboot when prompted

2. Connect a TFTP server reachable at 192.168.1.0/24
   (e.g. 192.168.1.66) to the ethernet port. Serve the OpenWrt
   initramfs image as "openwrt.bin"

3. To test OpenWrt only, go to step 4 and never execute step 5;
   To install, auto_recovery should be disabled first, and boot_part
   should be set to 1 if its current value is not.

   ath> setenv auto_recovery no
   ath> setenv boot_part 1
   ath> saveenv

4. Boot the initramfs image using U-Boot

   ath> setenv serverip 192.168.1.66
   ath> tftpboot 0x84000000 openwrt.bin
   ath> bootm

5. Copy the OpenWrt sysupgrade image to the device using scp and
   install it like a normal upgrade (with no need to keeping config
   since no config from "previous OpenWRT installation" could be kept
   at all)

   # sysupgrade -n /path/to/openwrt/sysupgrade.bin

Note: Like many other routers produced by Linksys, it has a dual
      firmware flash layout, but because I do not know how to handle
      it, I decide to disable it for more usable space. (That is why
      the "auto_recovery" above should be disabled before installing
      OpenWRT.) If someone is interested in generating factory
      firmware image capable to flash from stock firmware, as well as
      restoring the dual firmware layout, commented-out layout for the
      original secondary partitions left in the device tree may be a
      useful hint.

Installation from Web Interface
------------

1. Login to the router via its web interface (default password: admin)

2. Find the firmware update interface under "Connectivity/Basic"

3. Choose the OpenWrt factory image and click "Start"

4. If the router still boots into the stock firmware, it means that
   the OpenWrt factory image has been installed to the secondary
   partitions and failed to boot (since OpenWrt on EA4500 v3 does not
   support dual boot yet), and the router switched back to the stock
   firmware on the primary partitions. You have to install a stock
   firmware (e.g. 3.1.6.172023, downloadable from
   https://www.linksys.com/support-article?articleNum=148385 ) first
   (to the secondary partitions) , and after that, install OpenWrt
   factory image (to the primary partitions). After successful
   installation of OpenWrt, auto_recovery will be automatically
   disabled and router will only boot from the primary partitions.

6cffcb2e9f ath79: support Ruckus ZoneFlex 7321
Ruckus ZoneFlex 7321 is a dual-band, single radio 802.11n 2x2 MIMO enterprise
access point. It is very similar to its bigger brother, ZoneFlex 7372.

Hardware highligts:
- CPU: Atheros AR9342 SoC at 533 MHz
- RAM: 64MB DDR2
- Flash: 32MB SPI-NOR
- Wi-Fi: AR9342 built-in dual-band 2x2 MIMO radio
- Ethernet: single Gigabit Ethernet port through AR8035 gigabit PHY
- PoE: input through Gigabit port
- Standalone 12V/1A power input
- USB: optional single USB 2.0 host port on the 7321-U variant.

Serial console: 115200-8-N-1 on internal H1 header.
Pinout:

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
  adapter, TFTP server,  and removing a single T10 screw,
  but with much less manual steps, and is generally recommended, being
  safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
  work on some rare versions of stock firmware. A more involved, and
  requires installing `mkenvimage` from u-boot-tools package if you
  choose to rebuild your own environment, but can be used without
  disassembly or removal from installation point, if you have the
  credentials.
  If for some reason, size of your sysupgrade image exceeds 13312kB,
  proceed with method [1]. For official images this is not likely to
  happen ever.

[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7321-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7321_fw1_backup.bin
   $ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7321_fw2_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7321_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7321_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7321_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7321_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7321_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init
baudrate=115200
ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee
mtdparts=mtdparts=ar7100-nor0:256k(u-boot),13312k(rcks_wlan.main),2048k(datafs),256k(u-boot-env),512k(Board Data),13312k(rcks_wlan.bkup)
mtdids=nor0=ar7100-nor0
bootdelay=2
ethact=eth0
filesize=78a000
fileaddr=81000000
partition=nor0,0
mtddevnum=0
mtddevname=u-boot
ipaddr=10.0.0.1
serverip=10.0.0.5
stdin=serial
stdout=serial
stderr=serial

   These are the defaults, you can use most likely just this as input to
   mkenvimage.

   Now, create environment image and copy it over to TFTP root:

   $ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin -g 10.42.0.1

   Vverify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:
   mtd write ruckus_zf7321_fw1_backup.bin /dev/mtd1
   mtd write ruckus_zf7321_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
- The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
  execute the following command before booting:
  mw.l 1804006c 40
  And also you need to disable the reset button in device tree if you
  intend to debug Linux, because reset button on GPIO0 shares the TCK
  pin.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.

  proceed with method [1]. For official images this is not likely to
  happen ever.

[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0x9f040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7372-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7372_fw1_backup.bin
   $ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7372_fw2_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin

[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
   it boots, hold the reset button near Ethernet connectors for 5
   seconds.

1. Connect the device to the network. It will acquire address over DHCP,
   so either find its address using list of DHCP leases by looking for
   label MAC address, or try finding it by scanning for SSH port:

   $ nmap 10.42.0.0/24 -p22

   From now on, we assume your computer has address 10.42.0.1 and the device
   has address 10.42.0.254.

2. Set up a TFTP server on your computer. We assume that TFTP server
   root is at /srv/tftp.

3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
   frmware is pretty ancient and requires enabling HMAC-MD5.

   $ ssh 10.42.0.254 \
   -o UserKnownHostsFile=/dev/null \
   -o StrictHostKeyCheking=no \
   -o MACs=hmac-md5

   Login. User is "super", password is "sp-admin".
   Now execute a hidden command:

   Ruckus

   It is case-sensitive. Copy and paste the following string,
   including quotes. There will be no output on the console for that.

   ";/bin/sh;"

   Hit "enter". The AP will respond with:

   grrrr
   OK

   Now execute another hidden command:

   !v54!

   At "What's your chow?" prompt just hit "enter".
   Congratulations, you should now be dropped to Busybox shell with root
   permissions.

4. Optional, but highly recommended: backup the flash contents before
   installation. At your PC ensure the device can write the firmware
   over TFTP:

   $ sudo touch /srv/tftp/ruckus_zf7372_firmware{1,2}.bin
   $ sudo chmod 666 /srv/tftp/ruckus_zf7372_firmware{1,2}.bin

   Locate partitions for primary and secondary firmware image.
   NEVER blindly copy over MTD nodes, because MTD indices change
   depending on the currently active firmware, and all partitions are
   writable!

   # grep rcks_wlan /proc/mtd

   Copy over both images using TFTP, this will be useful in case you'd
   like to return to stock FW in future. Make sure to backup both, as
   OpenWrt uses bot firmwre partitions for storage!

   # tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7372_firmware1.bin -p 10.42.0.1
   # tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7372_firmware2.bin -p 10.42.0.1

   When the command finishes, copy over the dump to a safe place for
   storage.

   $ cp /srv/tftp/ruckus_zf7372_firmware{1,2}.bin ~/

5. Ensure the system is running from the BACKUP image, i.e. from
   rcks_wlan.bkup partition or "image 2". Otherwise the installation
   WILL fail, and you will need to access mtd0 device to write image
   which risks overwriting the bootloader, and so is not covered here
   and not supported.

   Switching to backup firmware can be achieved by executing a few
   consecutive reboots of the device, or by updating the stock firmware. The
   system will boot from the image it was not running from previously.
   Stock firmware available to update was conveniently dumped in point 4 :-)

6. Prepare U-boot environment image.
   Install u-boot-tools package. Alternatively, if you build your own
   images, OpenWrt provides mkenvimage in host staging directory as well.
   It is recommended to extract environment from the device, and modify
   it, rather then relying on defaults:

   $ sudo touch /srv/tftp/u-boot-env.bin
   $ sudo chmod 666 /srv/tftp/u-boot-env.bin

   On the device, find the MTD partition on which environment resides.
   Beware, it may change depending on currently active firmware image!

   # grep u-boot-env /proc/mtd

   Now, copy over the partition

   # tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1

   Store the stock environment in a safe place:

   $ cp /srv/tftp/u-boot-env.bin ~/

   Extract the values from the dump:

   $ strings u-boot-env.bin | tee u-boot-env.txt

   Now clean up the debris at the end of output, you should end up with
   each variable defined once. After that, set the bootcmd variable like
   this:

   bootcmd=bootm 0x9f040000

   You should end up with something like this:

bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init
baudrate=115200
ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee
bootdelay=2
mtdids=nor0=ar7100-nor0
mtdparts=mtdparts=ar7100-nor0:256k(u-boot),13312k(rcks_wlan.main),2048k(datafs),256k(u-boot-env),512k(Board Data),13312k(rcks_wlan.bkup)
ethact=eth0
filesize=1000000
fileaddr=81000000
ipaddr=192.168.0.7
serverip=192.168.0.51
partition=nor0,0
mtddevnum=0
mtddevname=u-boot
stdin=serial
stdout=serial
stderr=serial

   These are the defaults, you can use most likely just this as input to
   mkenvimage.

   Now, create environment image and copy it over to TFTP root:

   $ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
   $ sudo cp u-boot-env.bin /srv/tftp

   This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
   TFTP root:

   $ sudo cp openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin /srv/tftp

   Now load both to the device over TFTP:

   # tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
   # tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin -g 10.42.0.1

   Verify checksums of both images to ensure the transfer over TFTP
   was completed:

   # sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin

   And compare it against source images:

   $ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin

   Locate MTD partition of the primary image:

   # grep rcks_wlan.main /proc/mtd

   Now, write the images in place. Write U-boot environment last, so
   unit still can boot from backup image, should power failure occur during
   this. Replace MTD placeholders with real MTD nodes:

   # flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
   # flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>

   Finally, reboot the device. The device should directly boot into
   OpenWrt. Look for the characteristic power LED blinking pattern.

   # reboot -f

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Boot into OpenWrt initramfs as for initial installation. To do that
   without disassembly, you can write an initramfs image to the device
   using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
   fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
   before installation:
   mtd write ruckus_zf7372_fw1_backup.bin /dev/mtd1
   mtd write ruckus_zf7372_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.

Quirks and known issues:
- This is first device in ath79 target to support link state reporting
  on FE port attached trough the built-in switch.
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
  The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid   the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
  execute the following command before booting:
  mw.l 1804006c 40
  And also you need to disable the reset button in device tree if you
  intend to debug Linux, because reset button on GPIO0 shares the TCK
  pin.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.
  Source: https://alephsecurity.com/vulns/aleph-2019014
- Stock firmware has beamforming functionality, known as BeamFlex,
  using active multi-segment antennas on both bands - controlled by
  RF analog switches, driven by a pair of 74LV164 shift registers.
  Shift registers used for each radio are connected to GPIO14 (clock)
  and GPIO15 of the respective chip.
  They are mapped as generic GPIOs in OpenWrt - in stock firmware,
  they were most likely handled directly by radio firmware,
  given the real-time nature of their control.
  Lack of this support in OpenWrt causes the antennas to behave as
  ordinary omnidirectional antennas, and does not affect throughput in
  normal conditions, but GPIOs are available to tinker with nonetheless.

This image is supposed to be written with help of bootloader to the
flash, but as it stands, it's not aligned to block size and RedBoot will
happily create non-aligned partition size in FIS directory. This could
lead to kernel to mark the partition as read-only, therefore pad the

8e09f9ffc3 ath79: switch some RedBoot based devices to OKLI loader
After the kernel has switched version to 5.10, JA76PF2 and
RouterStations lost the capability to sysupgrade the OpenWrt version.
The cause is the lack of porting the patches responsible for partial
flash erase block writing and these boards FIS directory and RedBoot
config partitions share the same erase block. Because of that the FIS
directory can't be updated to accommodate kernel/rootfs partition size
changes. This could be remedied by bootloader update, but it is very
intrusive and could potentially lead to non-trivial recovery procedure,
if something went wrong. The less difficult option is to use OpenWrt
kernel loader, which will let us use static partition sizes and employ
mtd splitter to dynamically adjust kernel and rootfs partition sizes.
On sysupgrade from ath79 19.07 or 21.02 image, which still let to modify
FIS directory, the loader will be written to kernel partition, while the
kernel+rootfs to rootfs partition.

The caveats are:
* image format changes, no possible upgrade from ar71xx target images
* downgrade to any older OpenWrt version will require TFTP recovery or
  usage of bootloader command line interface

To downgrade to 19.07 or 21.02, or to upgrade if one is already on
OpenWrt with kernel 5.10, for RouterStations use TFTP recovery
procedure. For JA76PF2 use instructions from this commit message:
commit 0cc87b3bac ("ath79: image: disable sysupgrade images for routerstations and ja76pf2"),
replacing kernel image with loader (loader.bin suffix) and rootfs
image with firmware (firmware.bin suffix).

The MikroTik mAP-2nd (sold as mAP) is an indoor 2.4Ghz AP with
802.3af/at PoE input and passive PoE passthrough.

See https://mikrotik.com/product/RBmAP2nD for more details.

Specifications:
 - SoC: QCA9533
 - RAM: 64MB
 - Storage: 16MB NOR
 - Wireless: QCA9533 802.11b/g/n 2x2
 - Ethernet: 2x 10/100 ports,
    802.3af/at PoE in port 1, 500 mA passive PoE out on port 2
 - 7 user-controllable LEDs

Note: the device is a tiny AP and does not distinguish between both
ethernet ports roles, so they are both assigned to lan.
With the current setup, ETH1 is connected to eth1 and ETH2 is connected
to eth0 via the embedded switch port 2.

Flashing:
 TFTP boot initramfs image and then perform sysupgrade. The "ETH1" port
 must be used to upload the TFTP image. Follow common MikroTik procedure
 as in https://openwrt.org/toh/mikrotik/common.

Ubiquiti NanoBeam M5 devices are CPE equipment for customer locations
with one Ethernet port and a 5 GHz 300Mbps wireless interface.

Specificatons:

- Atheros AR9342
- 535 MHz CPU
- 64 MB RAM
- 8 MB Flash
- 1x 10/100 Mbps Ethernet with passive PoE input (24 V)
- 6 LEDs of which four are rssi
- 1 reset button
- UART (4-pin) header on PCB

Notes:

The device was supported by OpenWrt in ar71xx.

Flash instructions (web/ssh/tftp):

Loading the image via ssh vias a stock firmware prior "AirOS 5.6".
Downgrading stock is possible.

* Flashing is possible via AirOS software update page:
The "factory" ROM image is recognized as non-native and then installed correctly.
AirOS warns to better be familiar with the recovery procedure.

* Flashing can be done via ssh, which is becoming difficult due to legacy
keyexchange methods.

This is an exempary ssh-config:
KexAlgorithms +diffie-hellman-group1-sha1
HostKeyAlgorithms ssh-rsa
PubkeyAcceptedKeyTypes ssh-rsa
User ubnt

The password is ubnt.

Connecting via IPv6 link local worked best for me.

1. scp the factory image to /tmp
2. fwupdate.real -m /tmp/firmware_image_file.bin -d

6729fa2dd2 ath79: add support for TP-Link Deco M4R v1 and v2
This commit adds support for the TP-Link Deco M4R (it can also be M4,
TP-Link uses both names) v1 and v2. It is similar hardware-wise to the
Archer C6 v2. Software-wise it is very different. V2 has a bit different
layout from V1 but the chips are the same and the OEM firmware is the same
for both versions.

Specifications:
SoC: QCA9563-AL3A
RAM: Zentel A3R1GE40JBF
Wireless 2.4GHz: QCA9563-AL3A (main SoC)
Wireless 5GHz: QCA9886
Ethernet Switch: QCA8337N-AL3C
Flash: 16 MB SPI NOR

Flashing:

The device's bootloader only accepts images that are signed using
TP-Link's RSA key, therefore this way of flashing is not possible. The
device has a web GUI that should be accessible after setting up the device
using the app (it requires the app to set it up first because the web GUI
asks for the TP-Link account password) but for unknown reasons, the web
GUI also refuses custom images.

There is a debug firmware image that has been shared on the device's
OpenWrt forum thread that has telnet unlocked, which the bootloader will
accept because it is signed. It can be used to transfer an OpenWrt image
file over to the device and then be used with mtd to flash the device.

Pre-requisites:

- Debug firmware.
- A way of transferring the file to the router, you can use an FTP server
  as an example.
- Set a static IP of 192.168.0.2/255.255.255.0 on your computer.
- OpenWrt image.

Installation:

- Unplug your router and turn it upside down. Using a long and thin object
  like a SIM unlock tool, press and hold the reset button on the router and
  replug it. Keep holding it until the LED flashes yellow.
- Open 192.168.0.1. You should see the bootloader recovery's webpage.
  Choose the debug firmware that you downloaded and flash it. Wait until the
  router reboots (at this stage you can remove the static IP).

- Open a terminal window and connect to the router via telnet (the primary
  router should have a 192.168.0.1 IP address, secondary routers are
  different).
- Transfer the file over to the router, you can use curl to download it
  from the internet (use the insecure flag and make sure your source accepts
  insecure downloads) or from an FTP server.
- The router's default mtd partition scheme has kernel and rootfs
  separated. We can use dd to split the OpenWrt image file and flash it with
  mtd:

   dd if=openwrt.bin of=kernel.bin skip=0 count=8192 bs=256
   dd if=openwrt.bin of=rootfs.bin skip=8192 bs=256

- Once the images are ready, you have to flash the device using mtd
  (make sure to flash the correct partitions or you may be left with a
  hard bricked router):

   mtd write kernel.bin kernel
   mtd write rootfs.bin rootfs

- Flashing is done, reboot the device now.

ff9264fabc ath79: add support for Sophos AP100/AP55 family
The Sophos AP100, AP100C, AP55, and AP55C are dual-band 802.11ac access
points based on the Qualcomm QCA9558 SoC. They share PCB designs with
several devices that already have partial or full support, most notably the
Devolo DVL1750i/e.

The AP100 and AP100C are hardware-identical to the AP55 and AP55C, however
the 55 models' ART does not contain calibration data for their third chain
despite it being present on the PCB.

Specifications common to all models:
 - Qualcomm QCA9558 SoC @ 720 MHz (MIPS 74Kc Big-endian processor)
 - 128 MB RAM
 - 16 MB SPI flash
 - 1x 10/100/1000 Mbps Ethernet port, 802.3af PoE-in
 - Green and Red status LEDs sharing a single external light-pipe
 - Reset button on PCB[1]
 - Piezo beeper on PCB[2]
 - Serial UART header on PCB
 - Alternate power supply via 5.5x2.1mm DC jack @ 12 VDC

Unique to AP100 and AP100C:
 - 3T3R 2.4GHz 802.11b/g/n via SoC WMAC
 - 3T3R 5.8GHz 802.11a/n/ac via QCA9880 (PCI Express)

AP55 and AP55C:
 - 2T2R 2.4GHz 802.11b/g/n via SoC WMAC
 - 2T2R 5.8GHz 802.11a/n/ac via QCA9880 (PCI Express)

AP100 and AP55:
 - External RJ45 serial console port[3]
 - USB 2.0 Type A port, power controlled via GPIO 11

Flashing instructions:

This firmware can be flashed either via a compatible Sophos SG or XG
firewall appliance, which does not require disassembling the device, or via
the U-Boot console available on the internal UART header.

To flash via XG appliance:
 - Register on Sophos' website for a no-cost Home Use XG firewall license
 - Download and install the XG software on a compatible PC or virtual
   machine, complete initial appliance setup, and enable SSH console access
 - Connect the target AP device to the XG appliance's LAN interface
 - Approve the AP from the XG Web UI and wait until it shows as Active
   (this can take 3-5 minutes)
 - Connect to the XG appliance over SSH and access the Advanced Console
   (Menu option 5, then menu option 3)
 - Run `sudo awetool` and select the menu option to connect to an AP via
   SSH. When prompted to enable SSH on the target AP, select Yes.
 - Wait 2-3 minutes, then select the AP from the awetool menu again. This
   will connect you to a root shell on the target AP.
 - Copy the firmware to /tmp/openwrt.bin on the target AP via SCP/TFTP/etc
 - Run `mtd -r write /tmp/openwrt.bin astaro_image`
 - When complete, the access point will reboot to OpenWRT.

To flash via U-Boot serial console:
 - Configure a TFTP server on your PC, and set IP address 192.168.99.8 with
   netmask 255.255.255.0
 - Copy the firmware .bin to the TFTP server and rename to 'uImage_AP100C'
 - Open the target AP's enclosure and locate the 4-pin 3.3V UART header [4]
 - Connect the AP ethernet to your PC's ethernet port
 - Connect a terminal to the UART at 115200 8/N/1 as usual
 - Power on the AP and press a key to cancel autoboot when prompted
 - Run the following commands at the U-Boot console:
    - `tftpboot`
    - `cp.b $fileaddr 0x9f070000 $filesize`
    - `boot`
 - The access point will boot to OpenWRT.

MAC addresses as verified by OEM firmware:

use   address     source
LAN   label       config 0x201a (label)
2g    label + 1   art 0x1002    (also found at config 0x2004)
5g    label + 9   art 0x5006

Increments confirmed across three AP55C, two AP55, and one AP100C.

These changes have been tested to function on both current master and
21.02.0 without any obvious issues.

[1] Button is present but does not alter state of any GPIO on SoC
[2] Buzzer and driver circuitry is present on PCB but is not connected to
    any GPIO. Shorting an unpopulated resistor next to the driver circuitry
    should connect the buzzer to GPIO 4, but this is unconfirmed.
[3] This external RJ45 serial port is disabled in the OEM firmware, but
    works in OpenWRT without additional configuration, at least on my
    three test units.
[4] On AP100/AP55 models the UART header is accessible after removing
    the device's top cover. On AP100C/AP55C models, the PCB must be removed
    for access; three screws secure it to the case.
    Pin 1 is marked on the silkscreen. Pins from 1-4 are 3.3V, GND, TX, RX

85d581a64b ath79: Move TPLink WPA8630Pv2 to ath79-tiny target
These devices only have 6MiB available for firmware, which is not
enough for recent release images, so move these to the tiny target.

Note for users sysupgrading from the previous ath79-generic snapshot
images:

The tiny target kernel has a 4Kb flash erase block size instead
of the generic target's 64kb. This means the JFFS2 overlay partition
containing settings must be reformatted with the new block size or else
there will be data corruption.

To do this, backup your settings before upgrading, then during the
sysupgrade, de-select "Keep Settings". On the CLI, use "sysupgrade -n".

If you forget to do this and your system becomes unstable after
upgrading, you can do this to format the partition and recover:

* Reboot
* Press RESET when Power LED blinks during boot to enter Failsafe mode
* SSH to 192.168.1.1
* Run "firstboot" and reboot

    Click Continue to confirm
    wait about 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  Method 1: Serial to load Failsafe webpage (above)

  Method 2: delete a checksum from uboot-env
  this will make uboot load the failsafe image at next boot
  because it will fail the checksum verification of the image

    ssh into openwrt and run
    `fw_setenv rootfs_checksum 0`
    reboot, wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    select OEM firmware image and click upgrade

  Method 3: backup mtd partitions before upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs-kernel.bin to '0101A8C0.img'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot with serial console
  execute `tftpboot` and `bootm 0x81000000`

  NOTE: TFTP may not be reliable due to bugged bootloader
	set MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software is built using SDKs from Senao
  which is based on a heavily modified version
  of Openwrt Kamikaze or Altitude Adjustment.
  One of the many modifications is sysupgrade being performed by a custom script.
  Images are verified through successful unpackaging, correct filenames
  and size requirements for both kernel and rootfs files, and that they
  start with the correct magic numbers (first 2 bytes) for the respective headers.

  Newer Senao software requires more checks but their script
  includes a way to skip them.

  The OEM upgrade script is at
  /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be less than 1536k
  and the OEM upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied at the PHY side,
  using the at803x driver `phy-mode` setting through the DTS.
  Therefore, the Ethernet Configuration registers for GMAC0
  do not need the bits for RGMII delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

9c335accfe ath79: add support for TP-Link Archer A9 v6
TP-Link Archer A9 v6 (FCCID: TE7A9V6) is an AC1900 Wave-2 gigabit home
router based on a combination of Qualcomm QCN5502 (most likely a 4x4:4
version of the QCA9563 WiSOC), QCA9984 and QCA8337N.

The vendor's firmware content reveals that the same device might be
available on the US market under name 'Archer C90 v6'. Due to lack of
access to such hardware, support introduced in this commit was tested
only on the EU version (sold under 'Archer A9 v6' name).

Based on the information on the PL version of the vendor website, this
device has been already phased out and is no longer available.

Specifications:

- Qualcomm QCN5502 (775 MHz)
- 128 MB of RAM (DDR2)
- 16 MB of flash (SPI NOR)
- 5x Gbps Ethernet (Qualcomm QCA8337N over SGMII)
- Wi-Fi:
  - 802.11b/g/n on 2.4 GHz: Qualcomm QCN5502* in 4x4:4 mode
  - 802.11a/n/ac on 5 GHz: Qualcomm QCA9984 in 3x3:3 mode
  - 3x non-detachable, dual-band external antennas (~3.5 dBi for 5 GHz,
    ~2.2 dBi for 2.4 GHz, IPEX/U.FL connectors)
  - 1x internal PCB antenna for 2.4 GHz (~1.8 dBi)
- 1x USB 2.0 Type-A
- 11x LED (4x connected to QCA8337N, 7x connected to QCN5502)
- 2x button (reset, WPS)
- UART (4-pin, 2.54 mm pitch) header on PCB (not populated)
- 1x mechanical power switch
- 1x DC jack (12 V)

  *) unsupported due to missing support for QCN550x in ath9k

UART system serial console notice:

The RX signal of the main SOC's UART on this device is shared with the
WPS button's GPIO. The first-stage U-Boot by default disables the RX,
resulting in a non-functional UART input.
If you press and keep 'ENTER' on the serial console during early
boot-up, the first-stage U-Boot will enable RX input.

Vendor firmware allows password-less access to the system over serial.

Flash instruction (vendor GUI):

1. It is recommended to first upgrade vendor firmware to the latest
   version (1.1.1 Build 20210315 rel.40637 at the time of writing).
2. Use the 'factory' image directly in the vendor's GUI.

Flash instruction (TFTP based recovery in second-stage U-Boot):

1. Rename 'factory' image to 'ArcherA9v6_tp_recovery.bin'
2. Setup a TFTP server on your PC with IP 192.168.0.66/24.
3. Press and hold the reset button for ~5 sec while turning on power.
4. The device will download image, flash it and reboot.

Flash instruction (web based recovery in first-stage U-Boot):

1. Use 'CTRL+C' during power-up to enable CLI in first-stage U-Boot.
2. Connect a PC with IP set to 192.168.0.1 to one of the LAN ports.
3. Issue 'httpd' command and visit http://192.168.0.1 in browser.
4. Use the 'factory' image.

If you would like to restore vendor's firmware, follow one of the
recovery methods described above.

7ac8da0060 ath79: support ZTE MF286A/R
ZTE MF286A and MF286R are indoor LTE category 6/7 CPE router with simultaneous
dual-band 802.11ac plus 802.11n Wi-Fi radios and quad-port gigabit
Ethernet switch, FXS and external USB 2.0 port.

Hardware highlights:
- CPU: QCA9563 SoC at 775MHz,
- RAM: 128MB DDR2,
- NOR Flash: MX25L1606E 2MB SPI Flash, for U-boot only,
- NAND Flash: W25N01GV 128MB SPI NAND-Flash, for all other data,
- Wi-Fi 5GHz: QCA9886 2x2 MIMO 802.11ac Wave2 radio,
- WI-Fi 2.4GHz: QCA9563 3x3 MIMO 802.11n radio,
- Switch: QCA8337v2 4-port gigabit Ethernet, with single SGMII CPU port,
- WWAN:
  [MF286A] MDM9230-based category 6 internal LTE modem
  [MF286R] PXA1826-based category 7 internal LTE modem
  in extended  mini-PCIE form factor, with 3 internal antennas and
  2 external antenna connections, single mini-SIM slot.
- FXS: one external ATA port (handled entirely by modem part) with two
  physical connections in parallel,
- USB: Single external USB 2.0 port,
- Switches: power switch, WPS, Wi-Fi and reset buttons,
- LEDs: Wi-Fi, Test (internal). Rest of LEDs (Phone, WWAN, Battery,
  Signal state) handled entirely by modem. 4 link status LEDs handled by
  the switch on the backside.
- Battery: 3Ah 1-cell Li-Ion replaceable battery, with charging and
  monitoring handled by modem.
- Label MAC device: eth0

The device shares many components with previous model, MF286, differing
mostly by a Wave2 5GHz radio, flash layout and internal LED color.
In case of MF286A, the modem is the same as in MF286. MF286R uses a
different modem based on Marvell PXA1826 chip.

Internal modem of MF286A is supported via uqmi, MF286R modem isn't fully
supported, but it is expected to use comgt-ncm for connection, as it
uses standard 3GPP AT commands for connection establishment.

Console connection: connector X2 is the console port, with the following
pinout, starting from pin 1, which is the topmost pin when the board is
upright:
- VCC (3.3V). Do not use unless you need to source power for the
  converer from it.
- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.

Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.

STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.

STEP 1: gaining root shell:

Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.

Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
  then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
  "http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.

Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.

- Set IP of your computer to 192.168.0.22. (or appropriate subnet if
  changed)
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
  https://busybox.net/downloads/binaries/1.21.1/busybox-mips
  and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
  filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
  field named "addURLFilter", so it looks like this:
  <input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
    class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.0.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
  execute it. You should be able to log in at port 23, using
  "admin/admin" as credentials.

Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.

STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.
It is highly recommended to perform backup using both methods, to avoid
hassle of reassembling firmware images in future, if a restore is
needed.

Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:

  ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
  ssh root@192.168.1.1: cat /dev/mtd9 > mtd9_ubi.bin

And keep them in a safe place, should a restore be needed in future.

Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
  port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:

  cat /proc/mtd

  It should show the following:
  mtd0: 000a0000 00010000 "u-boot"
  mtd1: 00020000 00010000 "u-boot-env"
  mtd2: 00140000 00010000 "reserved1"
  mtd3: 000a0000 00020000 "fota-flag"
  mtd4: 00080000 00020000 "art"
  mtd5: 00080000 00020000 "mac"
  mtd6: 000c0000 00020000 "reserved2"
  mtd7: 00400000 00020000 "cfg-param"
  mtd8: 00400000 00020000 "log"
  mtd9: 000a0000 00020000 "oops"
  mtd10: 00500000 00020000 "reserved3"
  mtd11: 00800000 00020000 "web"
  mtd12: 00300000 00020000 "kernel"
  mtd13: 01a00000 00020000 "rootfs"
  mtd14: 01900000 00020000 "data"
  mtd15: 03200000 00020000 "fota"
  mtd16: 01d00000 00020000 "firmware"

  Differences might indicate that this is NOT a MF286A device but
  one of other variants.
- Copy over all MTD partitions, for example by executing the following:

  for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15; do cat /dev/mtd$i > \
  /var/usb_disk/mtd$i; done

  "Firmware" partition can be skipped, it is a concatenation
  of "kernel" and "rootfs".

- If the count of MTD partitions is different, this might indicate that
  this is not a MF286A device, but one of its other variants.
- (optionally) rename the files according to MTD partition names from
  /proc/mtd
- Unmount the filesystem:

  umount /var/usb_disk; sync

  and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
  firmware. This is especially important, because stock firmware for
  this device is not available officially, and is usually customized by
  the mobile providers.

STEP 3: Booting initramfs image:

Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
  set your computer's IP address as 192.168.0.22. This is the default
  expected by U-boot. You may wish to change that, and alter later
  commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:

  setenv serverip 192.168.0.22
  setenv ipaddr 192.168.0.1
  tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin
  bootm 0x81000000

  (Replace server IP and router IP as needed). There is no  emergency
  TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
  installation.

Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- After backing up the previous MTD contents, write the images to the
  "firmware" MTD device, which conveniently concatenates "kernel" and
  "rootfs" partitions that can fit the initramfs image:

  nandwrite -p /dev/<firmware-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286a-initramfs-kernel.bin

- If write is OK, reboot the device, it will reboot to OpenWrt
  initramfs:

  reboot -f

- After rebooting, SSH into the device and use sysupgrade to perform
  proper installation.

Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
  flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
  and name it root_uImage:

  dd if=/dev/zero of=padding.bin bs=8M count=1

  cat padding.bin openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin >
  root_uImage

- Set up a TFTP server at 192.0.0.1/8. Router will use random address
  from that range.
- Put the previously generated "root_uImage" into TFTP server root
  directory.
- Deliberately erase "kernel" partition" using stock firmware after
  taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
  initramfs image, which will let you perform actual installation using
  sysupgrade. This might take a considerable time, sometimes the router
  doesn't establish Ethernet link properly right after booting. Be
  patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
  light up. At this moment, perform power-on reset, and wait for OpenWrt
  initramfs to finish booting. Then proceed to actual installation.

STEP 4: Actual installation:
- Set your computer IP to 192.168.1.22/24
- scp the sysupgrade image to the device:

  scp openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin \
  root@192.168.1.1:/tmp/

- ssh into the device and execute sysupgrade:

  sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin

- Wait for router to reboot to full OpenWrt.

STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:

config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth '<auth>' # As required, usually 'none'
        option pincode '<pin>' # If required by SIM
        option apn '<apn>' # As required by ISP
        option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'

For example, the following works for most polish ISPs
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth 'none'
        option apn 'internet'
        option pdptype 'ipv4'

The required minimum is:
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
In this case, the modem will use last configured APN from stock
firmware - this should work out of the box, unless your SIM requires
PIN which can't be switched off.

If you have build with LuCI, installing luci-proto-qmi helps with this
task.

Restoring the stock firmware:

Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware
The only partitions you really care about are "web", "kernel", and
"rootfs". These are required to restore the stock firmware through
factory TFTP recovery.

Because kernel partition was enlarged, compared to stock
firmware, the kernel and rootfs MTDs don't align anymore, and you need
to carve out required data if you only have backup from stock FW:
- Prepare kernel image
  cat mtd12_kernel.bin mtd13_rootfs.bin > owrt_kernel.bin
  truncate -s 4M owrt_kernel_restore.bin
- Cut off first 1MB from rootfs
  dd if=mtd13_rootfs.bin of=owrt_rootfs.bin bs=1M skip=1
- Prepare image to write to "ubi" meta-partition:
  cat mtd6_reserved2.bi mtd7_cfg-param.bin mtd8_log.bin mtd9_oops.bin \
  mtd10_reserved3.bin mtd11_web.bin owrt_rootfs.bin > \
  owrt_ubi_ubi_restore.bin

You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.

Method 1: Using initramfs:
This method is recmmended if you took your backup from within OpenWrt
initramfs, as the reassembly is not needed.
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
  (scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
  mtd write <kernel_mtd> mtd4_kernel.bin
  rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
  restore them individually. Otherwise you might run out of space in
  tmpfs:

  (scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
  rm mtd3_ubiconcat0.bin

  (scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
  rm mtd5_ubiconcat1.bin

- If the write was correct, force a device reboot with

  reboot -f

Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
  your drive
- Mount your flash drive

  mkdir /tmp/usb

  mount /dev/sda1 /tmp/usb

- Remount your UBI volume at /overlay to R/O

  mount -o remount,ro /overlay

- Write back the kernel and ubi partitions from USB drive

  cd /tmp/usb
  mtd write mtd4_kernel.bin /dev/<kernel_mtd>

  mtd write mtd9_ubi.bin /dev/<kernel_ubi>

- If everything went well, force a device reboot with
  reboot -f

Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.

Method 3: using built-in TFTP recovery:
This method is recommended if you took backups using stock firmware.
- Assemble a recovery rootfs image from backup of stock partitions by
  concatenating "web", "kernel", "rootfs" images dumped from the device,
  as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
  TFTP pre-installation method.

Quirks and known issuesa
- It was observed, that CH340-based USB-UART converters output garbage
  during U-boot phase of system boot. At least CP2102 is known to work
  properly.
- Kernel partition size is increased to 4MB compared to stock 3MB, to
  accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
  image is at 2.5MB which is dangerously close to the limit. This has no
  effect on booting the system - but keep that in mind when reassembling
  an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
  you used before in stock firmware first. If you need to change it,
  please use protocok '3g' to establish connection once, or use the
  following command to change APN (and optionally IP type) manually:
  echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the blue debug LED hidden
  inside the case. All other LEDs are controlled by modem, on which the
  router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
  correct GPIO mapping. All other LEDs are controlled by modem,
  including this one in stock firmware. GPIO19, mapped there only acts
  as a gate, while the actual signal source seems to be 5GHz Wi-Fi
  radio, however it seems it is not the LED exposed by ath10k as
  ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
  reset of whole board, not only the modem. It is attached to
  gpio-restart driver, to restart the modem on reboot as well, to ensure
  QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
  for OpenWrt operation at all - have fun lurking around.
  The same modem module is used as in older MF286.

- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.

Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.

STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.

STEP 1: gaining root shell:

Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.

Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
  then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
  "http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.

Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.

- Set IP of your computer to 192.168.1.22.
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
  https://busybox.net/downloads/binaries/1.21.1/busybox-mips
  and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
  filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
  field named "addURLFilter", so it looks like this:
  <input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
    class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.1.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
  execute it. You should be able to log in at port 23, using
  "admin/admin" as credentials.

Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.

STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.

Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:

  ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
  ssh root@192.168.1.1: cat /dev/mtd8 > mtd8_ubi.bin

And keep them in a safe place, should a restore be needed in future.

Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
  port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:

  cat /proc/mtd

  It should show the following:
  mtd0: 00080000 00010000 "uboot"
  mtd1: 00020000 00010000 "uboot-env"
  mtd2: 00140000 00020000 "fota-flag"

  mtd11: 03200000 00020000 "fota"

  Differences might indicate that this is NOT a vanilla MF286 device but
  one of its later derivatives.
- Copy over all MTD partitions, for example by executing the following:

  for i in 0 1 2 3 4 5 6 7 8 9 10 11; do cat /dev/mtd$i > \
  /var/usb_disk/mtd$i; done

- If the count of MTD partitions is different, this might indicate that
  this is not a standard MF286 device, but one of its later derivatives.
- (optionally) rename the files according to MTD partition names from
  /proc/mtd
- Unmount the filesystem:

  umount /var/usb_disk; sync

  and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
  firmware. This is especially important, because stock firmware for
  this device is not available officially, and is usually customized by
  the mobile providers.

STEP 3: Booting initramfs image:

Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
  set your computer's IP address as 192.168.1.22. This is the default
  expected by U-boot. You may wish to change that, and alter later
  commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:

  setenv serverip 192.168.1.22
  setenv ipaddr 192.168.1.1
  tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin
  bootm 0x81000000

  (Replace server IP and router IP as needed). There is no  emergency
  TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
  installation.

Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- Split the image into two parts on 3MB partition size boundary, which
  is the size of kernel partition. Pad the output of second file to
  eraseblock size:

  dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
  bs=128k count=24 \
  of=openwrt-ath79-zte_mf286-intermediate-kernel.bin

  dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
  bs=128k skip=24 conv=sync \
  of=openwrt-ath79-zte_mf286-intermediate-rootfs.bin

- Copy over /usr/bin/flash_eraseall and /usr/bin/nandwrite utilities to
  /tmp. This is CRITICAL for installation, as erasing rootfs will cut
  you off from those tools on flash!

- After backing up the previous MTD contents, write the images to the
  respective MTD devices:

  /tmp/flash_eraseall /dev/<kernel-mtd>

  /tmp/nandwrite /dev/<kernel-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286-intermediate-kernel.bin

  /tmp/flash_eraseall /dev/<kernel-mtd>

  /tmp/nandwrite /dev/<rootfs-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286-intermediate-rootfs.bin

- Ensure that no bad blocks were present on the devices while writing.
  If they were present, you may need to vary the split  between
  kernel and rootfs parts, so U-boot reads a valid uImage after skipping
  the bad blocks. If it fails, you will be left with method 3 (below).
- If write is OK, reboot the device, it will reboot to OpenWrt
  initramfs:

  reboot -f

- After rebooting, SSH into the device and use sysupgrade to perform
  proper installation.

Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
  flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
  and name it root_uImage:

  dd if=/dev/zero of=padding.bin bs=8M count=1

  cat padding.bin openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin >
  root_uImage

- Set up a TFTP server at 192.0.0.1/8. Router will use random address
  from that range.
- Put the previously generated "root_uImage" into TFTP server root
  directory.
- Deliberately erase "kernel" partition" using stock firmware after
  taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
  initramfs image, which will let you perform actual installation using
  sysupgrade. This might take a considerable time, sometimes the router
  doesn't establish Ethernet link properly right after booting. Be
  patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
  light up. At this moment, perform power-on reset, and wait for OpenWrt
  initramfs to finish booting. Then proceed to actual installation.

STEP 4: Actual installation:
- scp the sysupgrade image to the device:

  scp openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin \
  root@192.168.1.1:/tmp/

- ssh into the device and execute sysupgrade:

  sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin

- Wait for router to reboot to full OpenWrt.

STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:

config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth '<auth>' # As required, usually 'none'
        option pincode '<pin>' # If required by SIM
        option apn '<apn>' # As required by ISP
        option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'

For example, the following works for most polish ISPs
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth 'none'
        option apn 'internet'
        option pdptype 'ipv4'

If you have build with LuCI, installing luci-proto-qmi helps with this
task.

Restoring the stock firmware:

Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware.
The only partitions you really care about are "web", "kernel", and
"rootfs". For easy padding and possibly restoring configuration, you can
concatenate most of them into images written into "ubi" meta-partition
in OpenWrt. To do so, execute something like:

cat mtd5_cfg-param.bin mtd6-oops.bin mtd7-web.bin mtd9-rootfs.bin > \
mtd8-ubi_restore.bin

You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.

Method 1: Using initramfs:
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
  (scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
  mtd write <kernel_mtd> mtd4_kernel.bin
  rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
  restore them individually. Otherwise you might run out of space in
  tmpfs:

  (scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
  rm mtd3_ubiconcat0.bin

  (scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
  rm mtd5_ubiconcat1.bin

- If the write was correct, force a device reboot with

  reboot -f

Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
  your drive
- Mount your flash drive

  mkdir /tmp/usb

  mount /dev/sda1 /tmp/usb

- Remount your UBI volume at /overlay to R/O

  mount -o remount,ro /overlay

- Write back the kernel and ubi partitions from USB drive

  cd /tmp/usb
  mtd write mtd4_kernel.bin /dev/<kernel_mtd>

  mtd write mtd8_ubi.bin /dev/<kernel_ubi>

- If everything went well, force a device reboot with
  reboot -f

Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.

Method 3: using built-in TFTP recovery (LAST RESORT):
- Assemble a recovery rootfs image from backup of stock partitions by
  concatenating "web", "kernel", "rootfs" images dumped from the device,
  as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
  TFTP pre-installation method.

Quirks and known issues
- Kernel partition size is increased to 4MB compared to stock 3MB, to
  accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
  image is at 2.5MB which is dangerously close to the limit. This has no
  effect on booting the system - but keep that in mind when reassembling
  an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
  you used before in stock firmware first. If you need to change it,
  please use protocok '3g' to establish connection once, or use the
  following command to change APN (and optionally IP type) manually:
  echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the green debug LED hidden
  inside the case. All other LEDs are controlled by modem, on which the
  router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
  correct GPIO mapping. All other LEDs are controlled by modem,
  including this one in stock firmware. GPIO19, mapped there only acts
  as a gate, while the actual signal source seems to be 5GHz Wi-Fi
  radio, however it seems it is not the LED exposed by ath10k as
  ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
  reset of whole board, not only the modem. It is attached to
  gpio-restart driver, to restart the modem on reboot as well, to ensure
  QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
  for OpenWrt operation at all - have fun lurking around.
- MAC address shift for 5GHz Wi-Fi used in stock firmware is
  0x320000000000, which is impossible to encode in the device tree, so I
  took the liberty of using MAC address increment of 1 for it, to ensure
  different BSSID for both Wi-Fi interfaces.

b21bc3479d ath79: ASUS RP-AC66 use flash till the end
This makes available the additional space,
which was occupied by OEM's jffs2 partition before:
"0x000000f80000-0x000001000000 : jffs2"

Reverting to the OEM firmware will also recover
this partition, i.e. it is not needed and can be
used by OpenWrt.
